The Halo Collar is capable of providing six types of feedback:

• Prevention Feedback — Warning, Boundary, and Emergency feedback
• Encouragement Feedback — Whistle, Good Dog, and Come Home feedback

Each type of feedback has predefined default settings, but you can customize the sounds, vibrations, or even static settings at any time. With a variety of sounds, vibration patterns, and static levels to choose from—including Cesar's various verbal feedback options and his famous "TSCH" sound—you have complete control over your dog's experience. With Cesar's guidance, you'll be able to set the best feedback for your dog's energy levels.

Note: In order for the static to work, you must install the metallic contact tips and both contact tips have to make contact with the skin.
